Ashton Kutcher and his wife Demi Moore have started a strict detox plan.

The 47-year-old actress and her 32-year-old spouse embarked on the Master Cleanse diet on Saturday, but Ashton has admitted he’s already finding it hard.

“9 hrs into the master cleanse. I want a steak, a beer, and a blow-pop. Hmmm this is gonna be rough (sic),” he wrote on his Twitter.

The plan, which is also known as the Maple Syrup diet, involves consuming nothing but a concoction of water, lemon, maple syrup and cayenne pepper and was famously used by Beyonce to slim down for her role in Dreamgirls.
While Ashton is struggling, Demi is faring slightly better: “2nd day of master cleanse and off to hike with hubby and the dogs. 2nd day better than the 1st! (sic).”

However, while many followers use the diet to lose weight - as the daily calorie consumption can be as low as 600 a day - Demi insists she’s not doing it for that reason.

“This is about health!!!”

When one of Demi’s followers Tweeted about the miserable side-effects when her own husband tried out the plan, the Ghost star replied, “That’s Y we R doing it 2gether! (sic).”
